This may be disappointing, but it’s not intended to be so as I still think it’s a worthwhile pursuit.
I use the Oura ring, which provides the same metrics you are describing. However, I’ve seen questionable correlation between those data points and my performance from a day to day basis. Perhaps that type of data is better viewed over the long haul as an indicator that you are making good lifestyle decisions. It definitely works for me for that purpose as I have made decisions that have improved those scores, but I still don’t use the data to plan a single workout.
